Pulling a Key

Pulling a good key entails a tradeoff: You want a solid contrast between the foreground black and background white while also preserving a nice feathered edge on the foreground so that it blends smoothly with the new background (the one that's replacing the green or blue you're removing). For this exercise, we'll be using Primatte RT, a sophisticated yet easy-to-use plug-in that comes bundled with Motion.
